"I had about given you up for lost," he said. "But you have arrived in the nick of time. A concerted German advance is expected momentarily, and without the reply you have brought we would have been at a great disadvantage."

Their mission successfully completed, the lads now hunted up Captain Derevaux. They found the young captain in his quarters. He jumped up as the two boys entered, ran hurriedly forward and greeted them effusively.

"Believe me, I am glad to see you again," he exclaimed. "I had made certain I would never see you alive."

"Oh, we are hard to get rid of," replied Hal, with a smile. "I guess we'll continue to stick around for some time yet."

"Well, you don't know how glad I am to see you back safely," continued the Frenchman. "But come in and tell me all about your journey."

For a long time the three talked; and then Hal bethought himself to ask concerning the situation in Liège.

"We are expecting an attack in force at almost any minute," explained the young captain; "and we are prepared to give a good account of ourselves. In spite of the fact that we are sure to be greatly outnumbered, there is no doubt that we can hold the forts. Of the city itself, I am not so certain, although these Belgians will fight to the last.

"Everything that can be done to strengthen our position has already been done, and all we can do now is to wait for the attack that must come soon. Already the German forces have delayed longer than had been anticipated, but every hour of delay makes our position that much stronger.

"British troops have been landed in France, and French and English both are hurrying to the support of the Belgians. It is impossible for them to arrive in time to take part in the coming fight, but it is the plan of the Belgians to delay the German advance as long as possible. Believe me, the Germans will find the Belgian defense such a stumbling-block as they have not counted upon."

"There is no question that they will fight to the last?" asked Hal.
